This manual describes the United Nations (UN) Military Logistics Unit, a unique entity that comes into existence only when peacekeeping contingencies require a military capability due to time constraints, security, logistical shortfalls, redeployment needs, budgetary constraints, difficult terrain, environment or weather. Under these conditions, the UN Military Logistics Unit offers an alternative capability to accomplish the needed tasks. For example, if the UN’s logistics system needs reinforcement, the Military Logistics Unit can be tasked to deploy its additional capacity in scalable and modular elements.
